what is dns and why should i check it?

DNS, short for Domain Name System, is a crucial part of how the Internet works. It's essentially a digital phonebook that connects domain names to the web servers that provide websites with content. Every website has an associated IP address and without DNS, you would have to type this number into your browser to access it – instead of simply typing in the domain name.

When you type in a domain name, DNS takes this and converts it into the IP address of your requested website so that you can access it. DNS is also responsible for filtering out malicious traffic and can block websites if required.

So why should you check your DNS? Well, there are numerous reasons why regular DNS checks are important:

1. Speed & Performance - Badly configured DNS servers can lead to slow loading times for websites and other online services. Regular checks ensure that the settings are optimal for smooth operation.

2. Security - As previously mentioned, DNS is responsible for filtering out malicious traffic from entering your network. Regular checks can detect any problems with your settings that could allow malicious content onto your system.

3. Reliability - An unreliable DNS server can lead to intermittent issues with connecting to certain websites and services due to incorrect settings or connections errors. Regular checks will ensure these ops roles get resolved quickly when they arise, reducing downtime and improving reliability in the long run.
